MR-ULINS: A Tightly-Coupled UWB-LiDAR-Inertial Estimator With Multi-Epoch Outlier Rejection
The LiDAR-inertial odometry (LIO) and the ultra-wideband (UWB) have been integrated to achieve driftless positioning in global navigation satellite system (GNSS)-denied environments. However, the UWB may be affected by systematic range errors (such as the clock drift and the antenna phase center off
